I've never seen this error message. There is one other thread on this forum that describes this error, but no useful solutions - you should probably contact NI support directly.
Do you get it when you try to run the vi. Your example code works fine on my system. Does this happen every time you use these functions? What happens if you create a new vi using this function (i.e. start from scratch - not cut and paste). If you always get this error, you may have a corrupt vi. You might try re-installing LV. Also, you say you're using version 6. There is an upgrade patch to 6.0.2 which is a free download. You should do this if you haven't already. Sorry I couldn't be more help. Tim
